東京計(jì)器葉片泵的安裝，

1油泵的支架座結(jié)構(gòu)要牢固，剛性好，并能充分吸收振動(dòng)，

2油泵可安裝成任何方向，泵和電機(jī)軸必須對(duì)正，同軸度應(yīng)控制在0.1mm以?xún)?nèi)，

3，吸入阻力不應(yīng)太高，以防產(chǎn)生空蝕現(xiàn)象。

4，注意進(jìn)油口處連接法蘭，接頭以及整個(gè)吸油管道必須密封，防止漏氣。

Features of TOKYO KEIKI / TOKIMEC Vane Pump

This high-pressure intra-vane pump range is specially developed for low-noise operating conditions.
Widely applied in hydraulic systems for injection molding machines, rubber processing equipment, die-casting machines and machine tools.
Built-in pressure pulsation damping structure drastically reduces flow pulsation, lowering operating noise and enabling smoother hydraulic performance.
Reinforced thick pump housing improves structural strength, shock resistance and noise attenuation performance.

Application Scope

Suitable as hydraulic component for ship machinery, injection molding machinery, rubber machinery, general hydraulic equipment, die-casting machines, plastic machinery, baling equipment, construction machinery, machine tools, mining equipment, hot-press machinery, shoe-making machinery, ceramic & brick forming machines, foaming equipment, forging machinery, fluidization equipment and metal stretching machinery.

Pump Installation Requirements

The pump support bracket shall be rigid and robust to effectively absorb operational vibration.
The pump can be mounted at any orientation; concentricity between pump shaft and motor shaft must be controlled within 0.1 mm.
Limit excessive suction resistance to avoid pump cavitation.
Ensure full sealing of suction flange, pipe fittings and entire suction pipeline to prevent air ingress.
